> If we start multiple `celery worker` on the same machine, each worker should have individual hostname to distinguish each other. Otherwise, some tools might not work correctly. E.g. celery flower would show only one worker if all workers are of the same hostname.
> It's necessary to have `--celery_hostname` or `-cn` option on `airflow worker` subcommand, and the option should accept an argument with the syntax as same as the option `-n` of `celery worker` command.

> airflow worker -c 1 -q highmem -cn highmem@%h
